The Relation of Health Anxiety to Treatment Utilization Among Patients with Substance Use Disorders: The Moderating Role of Racial/Ethnic Background

Background: Although health anxiety is broadly related to the overutilization of healthcare, limited research has examined this relation among individuals with substance use disorders (SUDs), or the extent to which racial/ethnic differences influence this relationship. Objectives: The purpose of the current study is to examine the moderating role of racial/ethnic minoritized background in the relationship between health anxiety and treatment utilization among individuals with SUDs. In the present study, patients with SUDs receiving residential treatment in Mississippi (N=118; 62% racial/ethnic minoritized status, 35.6% White) completed a measure of health anxiety and answered questions about past mental health, physical health, and substance use treatment. Regression models examined whether racial/ethnic minoritized status (White vs. racial/ethnic minoritized status) moderated the relation of health anxiety to treatment utilization among patients with SUDs. Treatment utilization was examined by asking whether participants had seen a doctor or mental health provider, engaged in substance use treatment, or alcohol treatment prior to their current treatment (dichotomous), as well as the number of times they had engaged in each treatment (physical health, mental health, substance use, and alcohol treatment) in the past year (continuous). Results: Results revealed that the facets of health anxiety involving concerns about pain and disease phobia were positively associated with treatment utilization, but only among racial/ethnic minoritized participants, with concerns about pain positively associated with self-reported physical health treatment utilization (OR=0.70, 95% CI=0.50; 0.97) and disease phobia positively associated with past mental health (B = 0.36, p = 0.023) and alcohol use treatment (B=-0.23, p=.009). Conversely, disease phobia was related to less prior alcohol use treatment among White participants (B=-0.23, p=.009). Conclusions: Overall, among patients in residential treatment for SUDs, racial/ethnic minoritized participants with SUDs reported more health anxiety compared to white participants, and certain facets of health anxiety (i.e., concerns about pain and worry about severe illness) were linked to heightened treatment utilization among racial/ethnic minoritized individuals.

The development and validation of a Chinese version of the Illness Attitude Scales: an investigation of university students

BACKGROUND

The Illness Attitude Scales (IAS) are considered as one of the most suitable instruments to screen hypochondriasis.

PURPOSE

Whether it has cross-cultural validity in China remains to be determined.

METHODS

In Chinese university students (141 women and 141 men), we have administered the IAS, the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ), and the Plutchik-van Praag Depression Inventory (PVP).

RESULTS

For the first time in Chinese culture, we have identified a four-factor structure of the IAS: patho-thanatophobia, symptom effect, treatment seeking, and hypochondriacal belief. Women scored significantly higher on IAS patho-thanatophobia and treatment seeking, on ZKPQ neuroticism-anxiety and activity, and on PVP than men did. The neuroticism-anxiety was significantly correlated with patho-thanatophobia and symptom effect, and PVP was positively correlated with symptom effect in women. Neuroticism-anxiety was significantly correlated with patho-thanatophobia, and impulsive sensation seeking and activity were significantly correlated with symptom effect in men.

CONCLUSION

In Chinese students, we have found a stable four-factor IAS structure.

Assessment of somatoform disorders: a review of strategies and instruments

We provide an overview of methods and instruments developed for the assessment of somatoform disorders. Four diagnostic purposes have been identified: (i) classification according to a diagnostic system; (ii) screening for probable cases; (iii) dimensional measurement of syndrome severity; and (iv) assessment of associated clinical features. Existing instruments designed for each of these strategies are described, including specifications of their psychometric properties, particular features, advantages and disadvantages. A conclusion of this review is that the currently existing 'family of assessment instruments' in the field of somatoform disorders should be used to improve the comparability of scientific findings in different cultures and settings.
